Class HttpSessionResolver

java.lang.Object

io.cettia.support.servlet.HttpSessionResolver

public class HttpSessionResolver
extends Object

A helper to resolve HttpSession from an application running on Servlet 3 and Java WebSocket API 1 environments.

In case of Java WebSocket API, HttpSession must be put into a map returned by EndpointConfig.getUserProperties() with the javax.servlet.http.HttpSession key when building ServerEndpointConfig.

 ServerEndpointConfig config = ServerEndpointConfig.Builder.create(AsityServerEndpoint.class,
 "/cettia")
 .configurator(new Configurator() {
      @Override
     protected <T> T getEndpointInstance(Class<T> endpointClass) throws
       InstantiationException {
       return endpointClass.cast(new AsityServerEndpoint().onwebsocket(wsTransportServer));
     }

      @Override
     protected void modifyHandshake(ServerEndpointConfig config, HandshakeRequest request,
                                    HandshakeResponse response) {
       HttpSession httpSession = (HttpSession) request.getHttpSession();
       config.getUserProperties().put(HttpSession.class.getName(), httpSession);
     }
 })
 .build();
